Oxalis bowiei Aiton ex G. Don, which is native to South Africa, is cultivated as an ornamental in China and is often persistent as a greenhouse weed.

Oxalis bulbifera X. S. Shen & H. Sun was described from a single collection in Anhui (Tiantangzhai), Shen Xian-sheng 20088 (holotype, KUN). The type specimen could not be traced in KUN, and no further material was available on contacting the authors. Although described as having affinities with Oxalis acetosella, it differs in several peculiar characteristics: the flowers are solitary or in pairs and the aerial stem is well developed. Even more unusual is the development at the leafless stem apex of "bracts" with bulbils in the axils. These are probably more accurately termed stipules, but the bulbils are a mystery. It is impossible to interpret this very unusual finding without recourse to herbarium material, and as such it is not included in the main account.

About 700 species: tropics and subtropics of both hemispheres but extending into temperate regions; eight species (two introduced) in China.
